In the course of the half century from 1844 onward, the population of Sonora increased materially, and carried more than a proportionate increase in the development of agricultural and mineral resources; and, especially under the beneficent Diaz régime, the state passed from the condition of a remote frontier province into that of a well-governed commonwealth. Naturally this progress carried the Caucasian element, including that of blended blood, farther and farther away from the nonprogressive Seri; and thereby the horror and detestation awakened by the very utterance of the name of the lowly tribe were intensified beyond description or ready understanding. The traditions of arrow poisoning were kept alive, and, doubtless, growing; the recitals of carrion eating were repeated, and possibly—just possibly—magnified beyond the reality; the accounts of offense and defense by nails and teeth (such as that of Jesus Omada) passed from mouth to mouth until—incredible as it may seem—the more timid Sonorenses stood in greater dread of these natural weapons of the Seri than of their brutal clubs and swift-thrown missiles, or even of their poisoned arrows; while traditions of cannibalism came up and received such general credence that the current items of Seri outrages, both in local gossip and in the Mexican and American press, customarily recounted savage butcheries ending with gruesome feastings on the raw or slightly cooked flesh of the victims. The shuddering antipathy felt for the perpetrators of these inhumanities even a thousand miles away increased toward their frontier, as light toward its source; the dread was deepened by the failure of punitive expeditions sent out again and again only to be balked by waterless sand-wastes or wrecking tiderips; and in 1894 and 1895, at least, the horror of the Seri was a daily and nightly incubus on half the citizens of Hermosillo and the tributary pueblos and ranchos, and a thorn in the flesh of the state officials.
